Suppose 2.57g of nickel(ii) chloride is dissolved in 350.ml of a 38.0mm aqueous solution of potassium carbonate. calculate the final molarity of nickel(ii) cation in the solution. you can assume the volume of the solution doesn't change when the nickel(ii) chloride is dissolved in it. be sure your answer has the correct number of significant digits.

Sorry I cant answer right now but tje answer is 1038.20m!

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
